Kaai Yukia

Kaai Yuko is based off Kaai Yuki and is unofficially her younger sister.

Design
Yuko is like a smaller version of Kaai Yuki, so she can be sometimes called Mini-Yuki. The clothing is the same, but her hair style is similar to Hatsune Miku's but her twin tails are shorter.

Personality
She is childish often, so she does duets with Yuki or Kaai Yui. She likes to learn about the staff (a musical term) and other stuff like notes, and etc.
